The Sumner Ultra Clamp will make your work more efficient on all of your pipe-to-pipe, pipe-to-fitting and pipe-to-flange fit-ups. The newly introduced Ultra Fit will assist you in those difficult fitting-to-fitting and fitting-to-flange fit-up situations. Aided by the robust acme thread, each set of Sumner flange pins will make two-holing a breeze. Sumner even includes the Professional Level which has one of the strongest magnets found and will give you that "third hand" in making a level fit-up.
